UPS/DK+3000VA - LEGRAND 310172.
- GENERAL FEATURES:
The Legrand UPS model Daker DK Plus 3000 is uninterruptible
power source with high frequency PWM technology, Double
Conversion On-Line, solid neutral, Rated Power 3,000 VA – 2700 W,
equipped with valve-regulated, hermetically-sealed accumulator
batteries, contained in a specific compartment inside the UPS or
in one or more external cabinets, sized to guarantee a minimum
uptime of 8 minutes at 80% of the load.
The electronics and batteries are contained in just two rack units.
The architecture of this UPS means it can be installed in either a
Tower configuration or inside Rack cabinets.
The rectifier of the UPS is comprised of a control and regulating
circuit (PFC), which, in addition to normal rectifier functions also:
• automatically corrects the power factor of the load to restore it to a
value of > 0.99 with a load applied at the output at 20% of the
rated load;
• power the inverter without requiring energy from the batteries,
even when there is very low voltage from the mains;
• ensures a total harmonic distortion of the input current THDIin
< 3% without the addition of filters or supplementary parts.
The bypass circuit is designed and built in compliance
with the following:
− Electromechanical switch
− Command and control logic managed by a microprocessor that:
• automatically transfers the load directly onto the primary mains
line without interrupting the power supply if any conditions of
overload, over temperature, continuous voltage outside of the
tolerances and inverter anomaly arise;
• automatically re-transfers the primary mains line load to an
inverter line, without interrupting the power supply, once
normal conditions of the load have been restored;
• if the primary mains line and the inverter are not synchronized,
the bypass must be disabled.
A diagnostic and shutdown software (UPS Communicator), if
accordingly installed in a PC connected to the UPS, which
allows you to access all of the DHEA's operational data, make
adjustments and settings to the special functions and control
Windows and Linux operating system shutdown.
An optional software (UPS management software) offers hierarchic
multiserver shutdown and remote management of the UPS for any
operating system in a heterogeneous network (Windows, Novell, Linux
and the common Unix).
Daker DK Plus 3000 is managed by a microprocessor and is able to
display, on a control panel and LCD screen, the alarms and
operating modes described below:
• normal operation
• output frequency that is not synchronized with the input
• battery-powered operation
• operation in bypass mode
• faulty power module
• overloaded
• generic anomaly
• incorrect neutral connection
• back-up time
• end of uptime
The Daker DK Plus 3000 Static Uninterruptible Power Supply bears
the CE marking pursuant to Directives 2014/35, 2104/30, and is
designed and built in compliance with the following standards:
• EN 62040-1 “General and safety requirements for UPSs used in
areas that are accessible to the operator”
• EN 62040-2 “Electromagnetic Compatibility requirements (EMC)”
• EN 62040-3 “Performance and test method requirements”.
